When we talk about the Internet industry, one of the inevitable topics is “roll-in”, and in the group of programmers, Android, is definitely the most roll-in.

Rise a few years ago, after all, the Android, entry threshold is low, training institute has trained a large number of Android development, primary front-end doesn’t lack on the market, many of them also to write some repetitive business in some small and medium-sized factory code, plus the back and there are more Android newcomer influx, inevitably got caught up in the high volume within the territory.

Therefore, many Android programmers are looking for a breakthrough, hoping to break through to the advanced or even expert Level Android, suddenly become a scarce talent market; Or I hope to be admitted to a big factory, where I can receive more formal and systematic vocational training, handle larger and more complex projects, and get in touch with more and more excellent colleagues and partners.

But this is not an easy thing, many Android programmers learn a little here and there, not a particular system, which leads to their weak technical foundation, do not know what big factory really want, plus they are far from big factory’s growth environment, Trying to grow and break through adversity on your own is like trying to find your way through the fog. It’s difficult and easy to give up halfway.

Here we have sorted out a growth path for senior mobile architects of Alibaba with an annual salary of 60W. Because the picture is too big to show only the headline, friends who need to move to the end of the article get the full version:

In the field of Android development, as early as at the end of 16, some people said that Android jobs are approaching saturation, more and more stringent recruitment requirements, as for now is a word against the principle of fresh students source code, on the one hand is indeed because of an industry from hot to calm, on the one hand is also more and more population in the city, More and more people engaged in Android development, resulting in more fierce competition in the market, at the same time, there were also many large factory layoffs, from then on, “Android cool” this sentence spread ten, ten hundred……

In fact, Android cool so many years, he really cool? High-end positions are still in short supply, and the recruitment market is often unable to find resumes with high salaries, such as high engineering, framework, audio and video, IoT. There are many high-paying positions, but few people can meet the job requirements.

In the final analysis, inner coil is a social phenomenon, but behind the inner coil, there are many people who say crazy inner coil, just to cover up their own technical strength is insufficient, I also sincerely hope, now reading this article is not what I said…

Only oneself core competitive ability promotion came up, ability won’t be rolled up

How to learn

At this time, many people will say, I am more than 30, can I still study, is it too late to study now?

The best time to plant a tree was ten years ago, the second best time is now.

It’s never too late to realize you need to learn.

Develop the habit of long-term learning and keep charging yourself, so that you can run faster and farther in your future career.

Then you are ready to study, but the difficulties come again: I have too many things to do every day at work, I can’t finish adding, deleting, modifying and checking, and the company and leaders do not support me to spend time on study. I still have the elderly and children to take care of at home. What should I do?

Learn this thing, first of all for yourself to learn, with the company and the boss has nothing to do.

You gain knowledge, your skills improve, and your boss can’t steal your knowledge. On the contrary, you have more confidence in the company and your boss.

Android has a long way to go, and we’re all on our way. Below is the latest learning materials, all materials are free to share, just need you to like support, and thenClick here toI can get it.

“When you are old and look back on your life, you will realize that the decision to study abroad, the decision to take your first job, the decision to fall in love, the decision to get married, and the decision to take time out to study are all huge changes in destiny. But standing at a fork in the road, the day you made your choice appears in your diary as a dull and ordinary day. I thought it was an ordinary day in my life.”

Now is a particularly good time to study, to study for a few months, to strengthen internal (technical ability) and external (interview experience). In the second half of the golden nine silver ten to find a better platform, get a better position, give yourself a better future.
